Nozzle changer issues on gsm1 | 19 April, 2016

Hi All,

I have been running into an issue where my gsm is not leaving an empty nozzle hole in changer 1 and is leaving two open in the other changer. The machine is attempting to change one of the nozzles 5-7 and leaving one open so no vacuum builds. I've manually tested the changer with discrete io and it all works fine. I'm not sure why this is happening. The configuration always matches what is on the head and in the changers so I don't know why it would do this. Worst part is it happen mid run and gets stuck as shown in the photo. I tried manually moving the nozzles back so there is one open hole per changer and adjusting the configuration but it keeps happening. Any idea what I'm doing wrong?

Try a nozzle changer teach. Machine will look for fids on the changer block. If that doesn't work, clean the rubber seals in the bottom of the block. No alcohol - dries them out. Might need to replace them if they are dry or cracked. Clean your nozzles (seals) and head where it contacts nozzles good. Nozzles could be sticking to the head somehow but not real likely.

Hi Swag,

Thanks for the suggestions. I did perform a changer teach on both changers successfully which resolved minor mis-alignment issues but not this problem. You can see in the photo that there are two open holes (5&6)and it is trying to drop a nozzle into hole 5 but vacuum will not build because no nozzle in hole 6. Maybe I should only have one hole open across both changers (one filled completely and the other only one hole open?)

Looks like that did it; I put another nozzle in hole 5, set the configuration and machine dry-cycled properly.

Yea! Sounds familiar that you'd need to do that. I haven't run GSM for a long time but sounds like something we had to do at some point.

Yeah, I think it has to do with both changers being owned by the one head. If each changer was owned by separate heads then they would each need an open hole.
